Υ射线或 EMS 处理蚕豆品种 Giza-2和 Rebaya-40的风干种子,两种诱变因素综合处理Giza-2。M_2代进行高产选择。M_3代以重复试验种植突变体。籽粒产量以单株计算。从每个群体的 M_3代得到的种子,随机取样测定。用凯氏法测定全粒种子和去皮籽粒豆粉的蛋白质含量。初步结果表明:同时增加蛋白质含量和籽粒产量以提高单株蛋白质产量是困难的。某些Υ射线诱发的突变体籽粒产量增加而蛋白质含量没有变化;某些 EMS 诱导的突变体蛋白质含量增加,而籽粒产量没有明显变化。综合处理产生的突变体,籽粒产量增加40%以上,而蛋白质含量减少约
Γ-ray or EMS treatment of the dried seeds of the broad bean varieties Giza-2 and Rebaya-40, and Giza-2 was synthesized by two mutagens. M_2 generation selection for high yield. M_3 generation replaces the mutant. Grain yield is calculated as individual plant. Seeds obtained from M_3 generations of each population were randomly sampled. Kjeldahl Determination of Protein Content of Whole Grain and Peeled Grain Flour. The preliminary results show that it is difficult to increase the protein content and grain yield simultaneously to increase the protein yield per plant. Some γ-induced mutants showed increased grain yield but no change in protein content; some EMS-induced mutants showed increased protein content with no significant change in grain yield. Synthetically generated mutants, grain yield increased more than 40%, while the protein content decreased by about
